airspirit You should be cleaning your tubing periodically. I am using the following: 70% distilled, 20% red glycol, 5% hyperlube, 5% sanitizer.

I would second the earlier motion for more detail on all of these (except the water )

I'm assuming 'red glycol' is antifreeze of some sort, but what brand, source, etc.

What is the sanitizer? (brand, source, etc.)

More details on Hyperlube (sources, etc) would even be helpful.

I have no bacterial growth in over 80-100ft of tubing and piping, and I have absolutely no corrosion. Further, there is no film on my tubing at this time. In a smaller system, use less sanitizer/ glycol and more hyperlube and you'll be fine. Remember, that stuff in my system lived through ALCOHOL ...

Ouch... Are you sure the deposit was living stuff, and not some kind of mineral/organic substance? Also what %age alcohol? As a home brewer I can tell you that some yeast strains will do very nicely in over 18% ethanol solutions

I don't think any additive other than the *sol enema would kill that stuff.

Is that the Pine-sol and Lysol blend I've heard about? If so, is there a more precise formula, or do you just dump in a good slug of each?

Thanks,
